I love Noelle, and I think it is fine for even a non-Christmas baby so long as the combo doesn't end up with a Xmas theme.
I have a cousin who has a birthday right around Xmas, and her name is Holly Noelle. Now, it might be a bit cliche, but it's definitely best for a December baby and not , say, a Fourth of July baby.
